This was a big week for new product announcements in the tech world, from a new PlayStation console to an HTC smartphone and the promise of cool new glasses from Google. Here's what you need to know about the week in Tech:

This week also marked the launch of a new smartphone from HTC. The company unveiled the "slim and stylish" HTC One at an event on Tuesday. USA TODAY's Ed Baig took a quick look at the device and said he likes what he's seen so far.

HTC One has a content-first approach, unlike other phones on the market. The phone has a home screen, BlinkFeed, which delivers a stream of news, social feeds and entertainment. Other features include a revamped camera, two forward-facing stereo speakers and interactive remote-control capabilities.

Check back soon for a full review from Baig.

3) Burger King hack

If you were on Twitter on Monday, you might have noticed a few strange Tweets from one of America's favorite fast-food chains. Burger King's Twitter account (@BurgerKing) was briefly hacked by Internet pranksters LulzSec for a little over an hour starting at noon.

The pranksters told the account's 85,000 followers that Burger King had been bought by McDonald's and changed @BurgerKing to @McDonalds. They also Tweeted using the hashtag #OpMadCow, unleashed a string of obscenities and posted that "if I catch you at a wendys, we're fightin!"

Burger King eventually regained control of the account and Tweeted later in the day: "Interesting day here at BURGER KING, but we're back! Welcome to our new followers. Hope you all stick around!"

Facebook and Apple are just two of an ever-growing list of companies that have been hacked in the past two weeks. The New York Times, Wall Street Journal, Twitter and the Federal Reserve have all been hit with hack attacks in the past month.

What does this all mean for the average user? Not much, for now. Facebook and Apple both emphasized that no user data were compromised in the attacks. But if hackers can easily get to employee data at these big-name companies, it's not a good sign.

5) Google introduces Project Glass and touch-screen Chromebook

Google was on a roll this week, with two big announcements about highly anticipated products.

On Wednesday, the company launched a website for Project Glass, its Internet eyeglasses, and released a video shot from the viewpoint of a user wearing the glasses. Users can give voice commands, check the weather, get directions and surf the Web from Google's glasses.

Later in the week, Google showed off the Chromebook Pixel, a touch-screen laptop with the highest resolution available on the market. Pixel has five hours of battery life, a Gorilla Glass screen, a slim body 1 terabyte of cloud storage (available for up to three years). The laptop is now available from $1,299.
